This is required when the UV calls H_SVM_INIT_DONE, and when a memory-slot is hotplugged to a Secure VM. Testing: Passed rigorous SVM reboot test using different sized SVMs. Changelog: . fixed a bug observed by Bharata. Pages that where paged-in and later paged-out must also be skipped from migration during H_SVM_INIT_DONE.
